Tenth time Assignment

1. There are 5 students, each of whom has a test score of 3 courses in Chinese, maths and foreign languages. Programming statistics The total score and average scores of each student and the average score of all students in each section. Requires that the results be initialized in the program, and the result is output in tabular form.                             

#include <stdio.h>intSumintscore[5][3],Doubleave[]);intMain () {intscore[5][3]={{Ten, -, -},{Ten, -, -},{Ten, -, -},{Ten, -, -},{Ten, -, -}}; inti,j,sum1,sum2,sum[5]; Doubleave1[5],ave2[3]; printf ("average scores of Chinese maths English");  for(i=0;i<5; i++) {sum1=0;  for(j=0;j<3; j + +) {sum1+=Score[i][j]; Sum[i]=sum1; } Sum[i]=sum1; Ave1[i]=(Double) sum1/3; }     for(j=0;j<3; j + +) {sum2=0;  for(i=0;i<5; i++) {sum2+=Score[i][j]; } Ave2[j]=(Double) sum2/5; }     for(i=0;i<5; i++) {printf ("First Class%d students", i+1);  for(j=0;j<3; j + +) {printf ("%d", Score[i][j]); } printf ("%d%.1f\n", Sum[i],ave1[i]); } printf ("Average score");  for(i=0;i<5; i++) {printf ("%.1f", Ave2[i]); } printf ("\ n"); return 0;}

2. Seek the sum of the elements of each row, column, and diagonal of any square.

# include <stdio.h># define M -intMain () {intI,j,m,sum1,sum2,sum3,sum4,sum[m][m]; printf ("the length of the input phalanx \ n"); scanf ("%d",&m);  for(i=0; i<m;i++) {printf ("Please enter the number in line%d: \ n", i+1);  for(j=0; j<m;j++) {scanf ("%d",&Sum[i][j]); }    }     for(i=0; i<m;i++) {sum1=0;  for(j=0; j<m;j++) {sum1+=Sum[i][j]; } printf ("line%d and is:%d\n", i+1, SUM1); }     for(j=0; j<m;j++) {sum2=0;  for(i=0; i<m;i++) {sum2+=Sum[i][j]; } printf ("the and of column%d is:%d\n", j+1, sum2); } sum3=0; SUM4=0;  for(i=0; i<m;i++) {sum3+=Sum[i][i]; SUM4+=sum[i][m-1-i]; } printf ("The sum of the diagonal is%d%d\n", SUM3,SUM4); return 0;}

Experimental conclusion: The storage of two-dimensional array is stored and output in the form of one-dimensional array;

Pay attention to the assignment value;

The subscript value should be within the range of the defined array size;

Notice that the array does not cross.
